Abstract

Disposizione di gruppo di filtraggio e procedimento per sigillare efficacemente un cappuccio terminale del filtro su un involucro, in cui il cappuccio terminale impegna il raccordo dell'involucro corna risultato della contrazione o dilatazione termica. La disposizione del gruppo di filtraggio comprende un gruppo di filtraggio disposto entro il percorso di flusso attraverso una camera dell'involucro di un gruppo di involucro. Il gruppo di involucro comprende almeno un'estensione, che è di forma sostanzialmente anulare e si estende entro la camera dell'involucro. L'estensione ha un foro interno che è disposto entro il percorso di flusso. Il gruppo di filtraggio ha almeno un cappuccio terminale avente un foro di forma sostanzialmente anulare ed è disposto entro la camera dell'involucro nel percorso di flusso. Il foro del cappuccio terminale e l'estensione di forma anulare sono impegnati tramite una tenuta che viene termicamente contratta o espansa a temperatura ambiente. Il diametro interno del foro del cappuccio terminale essendo minore del diametro esterno dell'estensione a temperatura ambiente, in modo che vi sia una interferenza tra il diametro interno ed il diametro esterno che provoca una sollecitazione nel cappuccio terminale e/oppure nel raccordo per mantenere l'integrità della tenuta.Arrangement of a filtering group and method for effectively sealing a filter end cap on a housing, in which the end cap engages the connection of the housing with the result of thermal contraction or expansion. The arrangement of the filter assembly comprises a filter assembly disposed within the flow path through a housing chamber of a housing assembly. The casing assembly comprises at least one extension, which is substantially annular in shape and extends within the casing chamber. The extension has an internal hole which is arranged within the flow path. The filtering unit has at least one end cap having a substantially annular shaped hole and is arranged within the chamber of the casing in the flow path. The hole of the end cap and the ring-shaped extension are engaged by means of a seal which is thermally contracted or expanded at room temperature. The internal diameter of the end cap hole being smaller than the external diameter of the extension at room temperature, so that there is an interference between the internal diameter and the external diameter which causes a stress in the end cap and / or in the fitting to maintain the integrity of the seal.
